TROLLEY-SWITCH.

Application filed June 1G, 1913.

T0 all /w/wnt it may concern.'

lle it known that 1, VILLIAM R. DAGGETT, citizen. of the United States, residing at Seattle, in the county of King and State of Washington, have invented a certain new and. useful Improvement in Trolley- Switches, of which the following is a specilisation.

My invention relates to improvements in automatic trolley guide-switches that may be disposed in a line of trolley wires of elec tric railmiys at the junctions of diverging lines, as where a. branchy line connects with a main line, and which are adapted tor op'- erate in response to the action of the trolleywheel of a car automatically to guide such trolley-wheel when passing such junction and cause itto maintain its engagement with that trolleywire that is disposed over that line of rails upon which such car is to continue its travel, and the object of my improvement is to provide a switch which shall be simple in its plan of construction, reliable in operation, easily installed/in its position in a line of trolley wire, and which shall be durable and of low electrical resist.

trated in the accompanying drawings, where1nf* y L Figure 1 illustrates by, a plan View the underside of a structure embodying my m-' vention, Fig. 2 is a view ini side elevation of the same, Fig. 3 is a fragmentary view, upon an enlarged scale, showing parts of. my invention in an inverted position, some of which yparts are illustrated in longitudinall verticalsection, Fig. i showsthe structure of Fig. 1 by a Lplan view of the upper side thereof, and Fig. 5 4is a view of the same upon an enlarged scale, on line fc, a; of Fig. el.. y

Like reference numerals indicate like parts throughout the drawings.

Referring to the drawings, 6 is a Y shaped l metal frame, preferably of copper, to give it low electrical resistance, having projecting arms 7, 8, and 9, the arm 7 as shown in Fig. 1, projecting from the left hand end of the frame 6, and the arm 8 projecting from the right hand of said frame 6, in a position directly in line with the arm 7, while the arm 9, projects from the same right hand end of said frame 6 in a direction to form an angle with relation to the line of arms 7 and 8 to produce the form of Specification of Letters Patent.

Serial No. 774,064.

a letter Y. Each of thearms 7, 8 and 9 have their end portions widened and fastened. thereon by screws 10, 10, 11, 11 and 12, 12 `respectively, are terminal brackets 13, 11 and 15 respectively, into each of which brackets 18, 1li and 15 is securely fixed and soldered an end of one of the trolley wires 16', 17 and 18, which is disposed to register with the rounded edge of an adjacent end of one of three ribs 19, 20 and 21 thaty project from and are integral with the respective arms 7,8 and 9.

Centrally disposed between the inner ends of ribs 19 and 20 is a like rib 22, and like-p` each of a length to provide space betweenk their ends and the ends of the ribs 19, 2O and 2 1 respectively, and within such spaces are disposed movable switch-arms 21, 25 and 26 respectively which have the same crosssectional shape as each of the ribs 19, 20, 21, and 23. These switch-arms 24, 25 and 26 are each pivoted at one end to the arms 7, S and 9 respectively, by pivot studs which are secured by screws, as shown more clearly 1n Fig. et, the switch-arm 21 being pivoted at its left hand end adjacent to the rib `19 while the switch-arms 25 and 26 are pivoted each at their right hand ends adjacent toribs 20 and 21 respectively,` whereby such switch-arms 241, 25 and 26 may each swing sidewise. l.

In the frame (5 are holes 27, 28 and 29 of the form of a segment of an annular ring, which holes 27, 28 and 29 respectively, are

disposed, as shown in Fig. 1, near the .free

each of the switch-arms 211, 25 and 26 may swing sidewise with but little friction, and fastened tc each of such projecting portions 30 is a screw-eye 33 to which a round belt 34 may be fastened, as more clearly shown in Fig. 4, such belt 34 being disposed .in connection with each of the screw-eyes 33 of the three switch-arms 24, 25 and 26 and to extend therefrom to engage with each of the pulleys 35, 36, 87 and 3S whereby when the switch-arm 24 is moved in either direction then the switch-arms 25 and 26 will be caused to swing sidewise in an opposite direction, and, conversely, when either of the switch-arms 25 or 26, is moved in either' direction, then both of them will swing in the same direction while the switch-arm 24 will swing in an opposite direction. Thus'ii' a car is moving toward the right hand with its trolley wheel engaged with trolley wire 16, then if such car proceeds in a straight line toward the trolley wire 17 with the switch-arm 24 in the position shown in Fig. 1, the trolley wheel of the car will act on such switch-arm 24 tol press and swing it to a position in line with the rib 22 while at the same time the switch arm 25 will be swung in the opposite direction to also come in line withvrib 22 and the rib 20, or if a car moves toward the left with its trolley wheel engaged with the trolley wire 17, when the switch-arm 25 is in position shown in Fig. 1, then such switch-arm 25 will be actuated by the trolley wheel to swing into line with rib 22 and motion will be connected through the round belt 34 to swing the switch-arm 24 into line with the same rib 22, and likewise if a car approaches the structure from the right with its trolley wheel on the trolley wire 18 its trolley wheel will act on the switch arm 26 to throw the switch-arms 24 and 26 in their proper relative positions to guide the trolley wheel in its travel to engage with the trolley wire 16 in an obvious manner.

What I claim is:

1. In an automatic trolley guide-switch, the combination with a frame-plate provided with a plurality of openings, of a plurality of terminal brackets adapted to be united with a trolley-wire, said terminal brackets being electrically connected with said frame-plates, fixed contact-ribs each disposed on said trame-plate between the ends of two of said terminal brackets and spaced therefrom, trolley contact-switch'- arms disposed one within each ot the spaces between the ends of said contact-ribs and said terminal brackets, each of said contact-switch-arms having one of its ends pivotally secured to said frame-plate at a point adjacent to one of said terminal brackets, a lug associated with the free end of each 0i said contact-switch-arrnsv and adapted to extend through the corresponding one of said openings in said frameplate, pulleys rotatably secured to said frame-plate, a belt associated with said pulleys, and means for attaching each of 4said lugs to said belt in such manner that when the free end of one of said contactswitch-arms is moved sidewise such movement shall be communicated to each of the other contact-switch-arms.

2. In an automatic trolley guide switch, a frame-plate provided on each of its ends with means for connecting it in circuit with a main line trolley wire and further provided on one of its ends with means for connecting it to a branch line trolley wire, fixed Contact ribs one disposed on said frame-plate in line with and between said main trolley wire connecting means and spaced therefrom, and the other in line with and between said branch-connecting means and one of vthe main end connecting means, trolley contact-switch-arms disposed one within each of the spaces between the ends of said contact ribs and the. ,.trolley wire connecting means each of said switcharms having one of its ends pivotally secured to said frame-plate atf'a"`point adjacent to its respective trolley-wire connecting means, openings provided in said frame-plate, lugs one associated with the free end of each of said switch-arms and adapted to project through the corresponding one of said openings, pulleys associated with said frame-plate, a belt associated with said pulleys and with said lugs whereby when one of said switch-arms is moved sidewise such movement shall be communicated to each of the other switch-arms.

In witness whereof, I, hereunto subscribe my name this 28th day of May, A. D. 1913.
